DRILLING-MACHINE.

SPECIFICATIONforming part of Letters Patent No. 322,969, dated July 28, 1885.

Application filed April 15, 1885.

To all whom it may concern.-

Be it known that I, GEORGE T. REIss, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Drilling Machines, of which the following is a specification.

This invention has reference to machines for drilling at once a large number of holes in one or more concentric circles.-

Certain modern ear-wheels consist of two webs of metal bolted to the sides of a flange upon the periphery of the hub and to the sides of a flange projecting inward from the tire, a third circle of holes for bolts being sometimes disposed through the webs at some point between the hub and flange. In some cases each circle of holes in such car-wheels contains a ditl'erent number of holes, and the radius of the circle of the two outer rows changes with the diameter of the car-wheels.

My machine is peculiarly adapted for the drilling of holes in such car-wheels.

My invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which- 7 Figure 1 is a front elevation of a drillingmachine illustrative of my improvements, the view exhibiting some of the upper portions of the machine in vertical section and also exhibiting the lower portions of the machine in half-vertical section; Fig. 2, a sectional plan of the machine with many parts on1itted,taken upon a line a little above the slotted disk Q, which supports the drill-spindles; Fig. 3, a sectional plan of the machine taken at a point just above the chuck F; Fig. 4, a sectional plan of the sliding block V,which carries the central circle of drill-spindles; and Fig. 5 a vertical section through the support of one of the drillspindlcs, showing the device for the independent vertical adjustment of one of the drills of the inner circle, the device for that purpose used in the outer circle of drills being similar.

Motion is transmitted to the machine by belts from any convenient driving-shaft to the top pulleys, p and n, soas to revolve the shaft a in one direction and the shaft 0 in the other direction. The shaft a rotates the central vertical shaft, Y, and, through the spurgearing Z d,the central circle of drill-spindles, c. The shaft 6 rotates the drill-spindles of the brackets through the medium of the gears f g Z j and the radialshaftsk. The pulleysqtransmit motion to the loose pulleys N at the base of the machine, the two base-pulleys obviously revolving in opposite directions. The drillspindles are to be fitted with chucks or sockets to receive the drills adapted for the work in hand. The wings P being opened outward, the table and chuck vare pulled forward, and the car-wheel or other article to be drilled is properly secured within the chuck, after which the table is again pushed inward, bringing the chucked work centrally under the system of drill-spindles, the wings P being then folded inward, so as not to interfere with the close approach of the attendant to the work. The work to be drilled being thus properly disposed beneath the drills, the shaft J is turned by a hand crank, thus rapidly elevating the bed D and the matter supported by it to a point within reach of the drills. The proper one of the pulleys N is now clutched to the shaft M, and the shaft J is locked against rotation by means of its clutch K. Under these conditions the bed-work will be automatically fed upward as the drilling proceeds. When the drills are through with this part of their work, motion in an opposite direction is given to the shaft M by releasing the pulley N which has been clutched to it, and clutching to it the other one ofthepulleys N. This gives to the bed,&c., a slow automatic descent. If a rapid descent be wanted, both pulleys Nare unclutched,the clutch Kreleased, and the bed fed downward rapidly by revolving the shaft J by hand. Through the levers O, with theirlinks and weight, the bed, Ste. ,is counterbalanced and rendered easy ofhand motion.

There are in the case illustrated twelve of the outer drill-spindles, h. In caseitis desired that the circle ofholes driven by these spindles shall contain twenty-four holes, twelve are first drilled in the manner described, and then the bed, &c., is lowered and the chuck properly rotated through the medium of pinion G so as to bring the twelve drilling-spindles to the proper position for the twelve new holes of the circle.

In the case of the car-wheels of the character hereinbefore described, the drill spindles h are set to drill their holes in the outer circle, and the central spindle-bearing block,V, is locked in its downward position so that the central circle of holes will be drilled simultaneously with one ofthe outer circles. When the chuck is partially rotated, so as to permit the outer spindles to drill new holes in their circle, the central circle of spindles must be gotten out of the way,so as to remain idle while the new outer holes are being drilled. This is accomplished by turning the shaftyso as to draw thelockingplungers inward, thus permitting the central block with its spindles to be pushed upward, so that the points of the central circle of drills will not come in contact with the work.

The twelve spindles h are to be set in atrue circle, and this circle can be enlarged or reduced at will by turning any one of the screws S, the annular gear T transmitting a uniform rotation of all of the screws, thus moving all of the bracketssimultaneously. By this means the diameter of the circle of the outer spindles is adjusted to suit car-wheels, 850., of varying diameters.

It is obvious that, in case less than twelve holes should be required in the outer circle, or less than nine in the inner circle, certain of the spindles may have the drills omitted, and that in all cases the number of spindles involved in the machine may be the subject of special consideration in designing the machine for special work.

When the outer circle of holes is of comparatively small diameter, or when there is to be an intermediate circle of holes, as mentioned in connection with the car-wheels hereinbefore described, it may be desirable that such comparativ ely small circle or such intermediate circle contain but half thenumber of holes of the larger or outermost circle. Provision is, therefore, made for moving alternate spindles of the outer circle of spindles inward or outward simultaneously independent of the other spindles of the outer series.

By inspecting Fig. 2 it will be observed that the screws S of the alternate brackets are provided with clutches U, by means of which the alternate screws can be released from their bevel-pinions which engage the annular gear T. These clutches being all released, it follows that the other spindles only partake of the simultaneous motion due to the presence of the annular gear. In this manner six of the spindles can be given a simultaneous radial adjustment, while the other six spindles remain in their old position orin any position into which they may be independently adjusted. The six brackets whose screws are provided with clutches may thus also be adjusted into a circle larger or smaller than the circle of the remaining spindles; and, the clutches being again engaged, the entire systern of outer spindles may be adjusted radially together, and in the same manner the clutchprovided brackets may be set in any relative radial position desired, either in a true circle or not, and the clutches may then be engaged so that the whole system moves together.

It will be observed in Fig. 2 that the alternate slots of the disk in which the brackets slide reach farther inward than the intermediate slots. By this means the alternate brackets can be moved radially inward to form a very small circle, while still leaving U the slots of sufficient width to accommodate bracketsof substantial dimensions. If all of the brackets were to be moved thus extreme ly inward, the slots would require to be of such limited width as to restrict the width of the brackets to an objectionable degree, and if the bracket-width be properly maintained the circle into which all of the spindles could be adjusted would not be probably of sufficiently small diameter.

In each bore of bracket or central spindlecarrying block is fitted atube, r,within which is formed the bearing for the drill-spindles. This tube is exteriorly threaded and provided with nuts by means of which it can be adjusted vertically and then securelyfixed. By this means the drill-spindles are all rendered independently adjustable vertically, so as to accommodate drills varyinga trifle in length, as wear or slight breakage at the point takes place, the desire being that all of the drills shall enter the work at once. This arrangement also makes provision for independently adjusting the vertical height of the various drills in case the article to be drilled presents surfaces on different planes. As the bearing'tubes adjust vertically in their bores the spindles slide in the driving-gears, being splined thereto.

It has been stated that the two pulleys N serve in rotating the worm-shaft M in either direction,according to whether the bed-work is to be raised or lowered by power. As a matter of fact, the bed-work will seldom, if ever, require to be lowered otherwise than by the hand-shaft, and in practice the two pulleys N will be driven in the same direction, one of the belts being crossed. This arrangement permits the power-feed to be operated when one of the series of spindles is standing still, as may often be the case where the machine is required for drilling one circle only of holes.
